This is a brand new Noveske upper. See below for the actual email from Noveske as to what it is

GEN I UPPER

KEYMOD NSR 7” HANDGUARD

7.5” STAINLESS STEEL, .750” GASBLOCK (caliber is found stamped on the barrel near the muzzle device)

KX3 FLASH HIDER (and old school one. Rad.)

Closest thing to this on their website is $1085, according to them (https://noveske.com/products/10-5-rogue-hunter-upper), but it's out of stock, and it doesn't have the KX3 flash hider, which is an easy $150 more.

This is brand new, available to ship right now or you can pick up locally. No CH or BCG
